Abstract

Nowadays composite materials have become more popular for its wide range of applications and design flexibility .Since the fuel costs are increasing day to day, most of the automobile industries are conducting various experiments to develop composites having less densities and superior mechanical and tribological properties which are equally cost effective. In view of the above, most of the research has been focused on improving mechanical and tribological properties of aluminium alloys by adding with ceramic reinforcements. Granite has a common form of igneous astound. It contain mostly of quartz with other minerals. It possesses high compressive strength, impervious and inflexible. Granite powder is most inexpensive as it comes as waste in granite cutting factories. Graphite is well known for its self-lubricating properties, which is a semi metal and an allotrope of carbon. Research was done to
improve the properties of aluminium using both graphite and granite as reinforcements separately. Till now, no work was done on the combination of both granite and graphite in a single composite. The present work mainly focuses on “Preparation &mechanical characterization for aluminium reinforced material metal matrix composite with granite & graphite as particulate material.”
